MMA World Rankings are comprised of all fighters, regardless of promotion. These rankings are sometimes referred to as "Global Rankings" or "Overall Rankings." RankingMMA has been publishing MMA world rankings since 2006.

So, how do we compile our rankings? What separates us from other web sites that formulate rankings?

Here is our rankings criteria:
- Most recent performance
- Performance against top competition
- Estimated ability against future competition
- Strength of competition
- Activity in the last 3 years
- Last 5 fights

There are many fighters sporting undefeated records from developing fight scenes, especially abroad. Something we take into consideration is the strength of competition they have faced. If a fighter has compiled a bunch of wins against competition that is lackluster they will likely have a difficult time moving up in the rankings until they face stiffer competition in order for us to accurately predict how they would perform against exceedingly tougher competition.

If a fighter has fought elite competition and fallen short, we factor in how they performed. If a fighter fairs well against a higher-ranked adversary, they could still move up in the rankings.

Actual fight footage is reviewed, regardless of promotion in order to formulate these rankings.

= Fighter moves up in the rankings after recent fight = Fighter moves down in the rankings after recent fight

Reasons a fighter is ineligible for Non-UFC Rankings (* = Not Ranked) = Inactivity over 15 months = Changing weight classes. A fighter must debut in their new weight class in order to officially be ranked there. Upon their debut, they will be removed from their former weight class. If the fighter temporarily competed outside of their division, they will be ranked in their primary division of choice. = Suspension. Should a fighter be suspended for performance enhancing substances or fighter conduct, they will be removed from the rankings.
